Title: Process for the separation of water-soluble salts of aromatic sulphonic acids from sulphonated mixtures
IPC: C07D221/10
Filed: 1981-05-05
Abstract: 1. A process for isolating liquid water-soluble salts of aromatic sulfonic acids from sulfonation mixtures, wherein a) the sulfonation mixture which is essentially free of unsulfonated starting material and other neutral substances is diluted with water to a sulfuric acid concentration of from 20 to 75% by weight, b) the diluted mixture is mixed with an amount, equivalent to the sulfonic acid, of a solvent-free, water-insoluble, open-chain, branched or linear, tertiary or secondary aliphatic amine of a total of 12 to 40 carbon atoms, which does not have an emulsifying action and which forms, with the sulfonic acid, a liquid salt which is sufficiently lipophilic that it separates spontaneously from the aqueous phase, c) the two resulting phases, which are of different density, are separated, d) the phase which consists of the lipophilic ammonium salt of the aromatic sulfonic acid is mixed, if necessary after having been washed with water, with the stoichiometric amount of a water-soluble base whose sulfonate is to be prepared, and with water, e) the two resulting phases are again separated and the salt is left in the aqueous solution or f) the salt is isolated by evaporation or by crystallization and decanting or filtering.

Title: Jointing fabrics
IPC: C09J7/35
Filed: 1982-06-02
Abstract: A tape 1 comprising a fibrous reinforcement, a layer of 
adhesive which can be activated by heat and a strip of 
metallic foil is heated by the passage of an electric current 
through the foil so as to activate the adhesive and is then 
pressed into contact with two pieces of fabric to be joined. 
The electric current passes along two conductors 4 from a 
power unit 3 supplied by a source 2 and is caused to flow for 
a length of time which is controlled in accordance with the 
average temperature reached by the foil as computed by a 
micro-processor 8 from the variation of its electrical resist­
ance derived from the potential drop across its ends for a 
predetermined current flow, tapped off by conductors 5. 
When the average temperature approaches a value corres­
ponding to full activation of the adhesive, an indication is 
provided to the operator by an indicator 9 and then, after an 
interval of time sufficient to allow the operator to press the 
tape against the loint between the two pieces of fabric, as 
measured by a timer 10, the current is automatically 
switched off by the microprocessor 8.

Abstract: The production of preformed solder material in the 
shape of, for example, rings or washers is effected in a more 
convenient and less costly manner by feeding a thickened 
fluxed solder paste on to a sheet carrier material, preferably 
a flexible carrier material, so as to deposit on the carrier 
material a plurality of the desired preformed shapes and then 
heating the preformed shapes on the carrier material so as to 
harden them and cause them to releasably adhere to the 
sheet of carrier material. The fluxed solder paste is fed on to 
the sheet of carrier material by a screen printing technique or 
by means of a stencil. When required for use, the preformed 
shapes of fluxed solder material can be peeled off the carrier 
sheet or, if the carrier material is a heat shrinkable plastics 
film, they can be positioned whilst still on the carrier material 
to which heat is then applied to cause the plastics film to 
shrink-wrap the soldering site.

IPC: B23K26/00
Filed: 1982-03-04
Abstract: The invention relates to a brush provided with bristles made of an organic thermoplastic synthetic material such as nylon, particularly a tooth-brush. The free ends of the bristles which are sharp and therefore able to damage soft surfaces are made round by a heat treatment. The bristle ends are preferably submitted to a laser beam treatment, the source of laser beams being preferably placed below the bristle ends. Particularly, the brush and the heat source are submitted to a relative movement and the heat treatment takes place in an atmosphere of an inert gas. The invention relates also to a brush, preferably a tooth brush, having a head carrying a plurality of monofilaments made of an organic thermoplastic synthetic material. The monofilaments are tangentially welded to each other in a hole provided in said head, so that a plurality of capillary channels is obtained, said channels being open, on the one hand, on the side where the filaments protrude from the brush head and, on the other hand, on the side of the brush head opposite to the side carrying the protruding monofilaments. Impurities may thus be removed through the open-ended capillary channels, when the brush is cleaned.
